Billionaire entrepreneur Elon Musk has been keeping the technology world on its toes for years, revolutionizing the electric car and private spaceflight industries with his Tesla and SpaceX companies and consistently staying ahead of the curve with innovation. On Monday, Musk will break with precedent once again. According to a report from Space.com, Musk plans to unveil a new travel technology called the “Hyperloop.”

Musk has been talking about the Hyperloop for over a year now, but despite his continued emotional investment in the technology, the public has still not seen an actual spec design. Supposedly, the Hyperloop would be an inexpensive solar-powered travel technology that would take passengers “from Los Angeles to San Francisco,” a 380+ mile trip, in less than half an hour. Musk has claimed that the Hyperloop would charge less for tickets than planes or trains, and that frequent departures would make the transportation method as viable as either.

The constant teasing from Musk has led numerous other innovators to try to figure out exactly how the Hyperloop would work, or what it would look like. Musk has described the transportation technology as a “cross between a Concorde and a rail gun and an air hockey table,” a description that led John Guardi, another entrepreneur, to draw up his own spec of the system. Guardi’s version, which uses air to propel passenger cars through tubes, got Musk’s attention and even inspired the billionaire to tweet that it was the closest anyone had gotten to his actual vision.

All of the mystery will come to a close Monday when Musk finally reveals his own innovation. However, just because Musk is finally going public with his idea doesn’t mean we should expect to be riding the Hyperloop in a matter of years. During a conference call last Tuesday, Musk said that he wanted to focus on Tesla and SpaceX, and that the Hyperloop, while a great idea, would take a lot of work to develop and turn into a reality.

Still, while Musk may not have the time right now to turn the Hyperloop into the greatest transportation innovation of the 21st century, he has a reason for going public with his design, and it goes beyond bragging rights or public relations stunt. Musk is putting his design out there in hopes that the world network of inventors and engineers will take it and make something happen. And who knows, if some aspiring scientist does move forward with the Hyperloop, Musk could be back in the picture from time to time to offer a helping hand.
